Set in what appears to be the entirely Anglo-Pakistani city of Bradford, England, the unlikely hero of [the comic] ”Vimanarama” is Ali, an angsty Shiite 19-year-old who gets caught up in an ancient war between pollution-loving demons and the Ultrahadeen, giant beings apparently inspired by two enduring myths: stories of angels in the Koran and elsewhere, and Jack Kirby’s ”The Eternals,” a mid-1970s comic about a race of superheroic immortals whom humans worship as gods.
